| +/**
|
| + * @group Polymer Core Elements
|
| + *
|
| + * The `core-iconset-svg` element allows users to define their own icon sets
|
| + * that contain svg icons. The svg icon elements should be children of the
|
| + * `core-iconset-svg` element. Multiple icons should be given distinct id's.
|
| + *
|
| + * Using svg elements to create icons has a few advantages over traditional
|
| + * bitmap graphics like jpg or png. Icons that use svg are vector based so they
|
| + * are resolution independent and should look good on any device. They are
|
| + * stylable via css. Icons can be themed, colorized, and even animated.
|
| + *
|
| + * Example:
|
| + *
|
| + * <core-iconset-svg id="my-svg-icons" iconSize="24">
|
| + * <svg>
|
| + * <defs>
|
| + * <g id="shape">
|
| + * <rect x="50" y="50" width="50" height="50" />
|
| + * <circle cx="50" cy="50" r="50" />
|
| + * </g>
|
| + * </defs>
|
| + * </svg>
|
| + * </core-iconset-svg>
|
| + *
|
| + * This will automatically register the icon set "my-svg-icons" to the iconset
|
| + * database. To use these icons from within another element, make a
|
| + * `core-iconset` element and call the `byId` method
|
| + * to retrieve a given iconset. To apply a particular icon inside an
|
| + * element use the `applyIcon` method. For example:
|
| + *
|
| + * iconset.applyIcon(iconNode, 'car');
|
| + *
|
| + * @element core-iconset-svg
|
| + * @extends core-meta
|
| + * @homepage github.io
